The Millet Aerial Max is made from a stretch version of Gore-Tex Paclite that feels very hard-wearing, while allowing a closer fit without restricting movement. There is also heat-sealed reinforcement on the shoulders. The body is quite short, which is good for climbers for example. The fabric is rated as extremely waterproof and extremely breathable so you should stay dry. The main chest pockets, which are mesh-lined for extra ventilation, are large and easily accessed while wearing a rucksack belt or climbing harness, while a third chest pocket is useful for smaller items. The hood rolls to the collar and can be secured in place, and when unrolled it fits the head very well and benefits from a stiffened peak and good movement. A tough jacket with lots of uses and is particularly good for climbers or mountaineers. But the Millet Aerial Max’s stretch fabric coupled with the close fit gives this a body-hugging feel that you may not like. There are lighter options too. The peak may be a bit too pointy to offer useful protection to the eyes. Jackets made from Pro Shell fabric control condensation better than the Paclite used here. There’s no reflective piping either.
